21、I .I .2 (2002-01) 1 Scope The present document specifies the stage 3 description of the Supplementary Service Include Call (SS-IC) for the Terrestrial Trunked Radio (TETRA). SS-IC permits the served user participating a call to include other participant to that call. Man-Machine Interface (MMI) and
22、charging principles are outside the scope of the present document. Supplementary service specifications are produced in three stages according to the method defined in ITU-T Recommendation 1.130 i. The stage 1 description specifies the service from the users point of view (see ETS 300 392-10-17 7).
23、The stage 2 description identifies the functional capabilities and the information flows needed to support the service as specified in its stage 1 description (see EN 300 392-1 1-17 SI). The present stage 3 description specifies the protocols at the air interface und ut the various Inter-System Inte
24、rfaces PSI) to support SS-IC. NOTE 1: According to ITU-T Recommendation I. 130 i, the stage 3 description of any telecommunication service addresses the network implementation aspects. Consequently it comprises two steps: the specifications of all protocols at the various reference points involved i
25、n any of the service procedures (notably the service operation) are the first step of the stage 3 description, and the specifications of the functions of the corresponding network entities are its second step. NOTE 2: The latter have not been provided since they can be derived from the specification
26、 of the functional entity actions in the stage 2 description. The present document is applicable to Voice plus Data individual and group calls; more specifically to the following entities: - the MS/LSs of the served user and of the affected user; and - the served user and the affected user Switching
27、 and Management Infrastructures (SwMIs) in an individual and group call. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

ETSI 8 ETSI EN 300 392-12-17 VI .I .2 (2002-01) Parameters 4 Request 4.1 Included party SS-IC service descripti
40、on M Gen eral SS-IC enables a served user, while already participating in an active call (original call) to place a second call and have the participant(s) in this second call included in a group call together with the participant(s) in the original call. This clause describes the SS-IC services off
41、ered by the Circuit Mode Control Entity (CMCE) at the Supplementary Services service access point (TNSS-SAP) of the TETRA voice plus data layer 3 service boundary in a TETRA Mobile Station (MS) or TETRA Line Station (LS). The SS-IC service access point is used in conformance testing as a normative b
42、oundary in MSs and LSs. NOTE: As the present document deals only with SS-IC, all the service primitives has been shown without a TNSS-IC- prefix e.g. the TNSS-IC-INVOKE request is shortened into an INVOKE request. 4.2 SS-IC services offered over the TNSS-SAP 4.2.1 General on service primitives NOTE:
43、 As man-machine interface or user applications are outside the scope of the present document service primitives are used to define information exchange to and from the standardized part of the MS/LS. Those primitives may be only indirectly accessible. The SS-IC service primitives at the served user
44、MS/LS TNSS-SAP shall be: - CANCEL request; - INVOKE request; - INVOKE indication; and - INVOCATION FAILURE indication. The SS-IC service primitives for the affected user at the MS/LS TNSS-SAP shall be: - INFORM indication. The SS-IC service primitives for another user at the MS/LS TNSS-SAP shall be:
45、 - INFORM indication. 4.2.2 CANCEL The CANCEL request primitive may be sent over the served user TNSS-SAP by the user application to the MS/LS CMCE to cancel SS-IC invocation. The CANCEL primitive shall contain the SS-IC parameters listed in table 1. ETSI 9 Parameters ETSI EN 300 392-12-17 VI .I .2
46、(2002-01) Request Indication 4.2.3 INFORM Included party The INFORM indication primitive may be sent over the affected or another user TNSS-SAP by the MS/LS CMCE to the user application to inform it that the presented call is an include call or that the current call is modified into an include call.
47、 M M There are no parameters in the INFORM indication primitive. NOTE: Actually the INFORM indication is carried as a notification indication of the basic call. Parameters Included party Invocation failure cause Disconnect cause 4.2.4 INVOKE Indication M M M The INVOKE request primitive shall be sen
48、t over the served user TNSS-SAP by the user application to the MS/LS CMCE to invoke SS-IC. The INVOKE indication shall be sent over the served user TNSS-SAP to the user application when the inclusion of the new party or parties has been completed. The INVOKE primitive shall contain the SS-IC paramet
49、ers listed in table 2. NOTE 1 : There are no other parameters as the call type is implied and the other relevant call parameters are the same as for the current call. NOTE 2: “called user alerted“ is conveyed using the basic call primitives. 4.2.5 INVOCATION FAILURE indication The INVOCATION FAILURE indication primitive may be sent over the served user TNSS-SAP by the MS/LS CMCE to the user application to inform it about the failure of a previous INVOKE request. The INVOCATION FAILURE indication primitive shall contain the SS-IC parameters listed in table 3. Table 3:
